I did some research on line and my magnesium was recommended to cause less diarrhea. So, I bought it, and then I recently read that it was the best type for neuropathy. It was just luck that is what I had bought. My doctor originally just recommended that I use magnesium, period., I hadn't taken any for about 7 months and my neuropathy was getting worse. I live alone out in the country and can't get fresh vegetable. I can shop at Costco and stock up on a bunch of frozen foods.
